How do I expand a storage pool in an HA cluster?

When adding new disks to a storage pool, you can add the disks to an existing RAID group in the pool or use the newly added disks to create a new RAID group in the pool.

1. Insert the new disks into the same disk slots on both the active and passive nodes.
   
   Important

   Disks in the same disk slot must be of the same capacity on both nodes.
2. Go to Storage Manager > Storage Space.
3. Identify the pool to expand.
4. Under Action, click > Expand Pool.
5. Select an expansion method:
   • Create and add a new RAID group
   • Add new disk(s) to an existing RAID group
     If you select this method, also select the RAID group to expand.
6. Click Next.
7. Select the disks to be added, and then click Next.
   
   Note

   If the new disks do not appear on the list, check whether they are properly inserted in the same slots on both the active and passive nodes. The system only shows disks that are installed in the same slots on both nodes.
8. On the Summary page, confirm the configuration and click Expand.
   The system expands the storage pool on both nodes.

1. Identify the RAID group in the storage pool you want to expand.
   1. Go to Storage Manager > Storage Space.
   2. Identify the storage pool to expand.
   3. Under Action, click > Manage, and then go to the RAID tab.
      Storage Manager displays the RAID groups in the storage pool, and the disks used by each RAID group.
2. Verify that the RAID group's RAID type is RAID 1, 5 or 6.
   
   Note

   Only these RAID types currently support expansion by replacing disks one by one.
3. Disable all spare disks assigned to the RAID group.
   1. Go to Storage Manager > Disks > Disk.
   2. Identify the spare disk.
   3. Under Action, click > Disable Spare.
4. Note down all disk slots used by the RAID group.
   
   Tip

   To check the disk slots used by the RAID group, go back to Storage Manager > Storage Space, identify the storage pool, click > Manage, and then go to the RAID tab.
5. On the passive node, replace the disks one at a time.
   1. Replace an existing disk with a new disk that has a greater capacity.
      
      Important

      Do not replace more than one disk at a time.
   2. Wait for the system to rebuild the RAID group and the storage pool.
      
      Tip

      You can monitor the rebuild process in Storage Manager or High Availability Manager.
   3. Once the rebuild process is done, verify that both the disk's and pool's statuses are healthy.
      You can check the disk status in Storage Manager > Disks > Disk, and the pool status in Storage Manager > Storage Space.
   4. Repeat the previous steps until all disks have been replaced.
6. On the active node, replace the disks one at a time.
   Follow the same steps for replacing the disks on the passive node.
   
   Important

   Ensure the capacity of the disk in each disk slot on the active node matches that of the corresponding disk slot on the passive node.
7. After successfully replacing all disks in the RAID group on both nodes, check the storage pool capacity in Storage Manager.
   Once the total capacity of the storage pool is updated, the expansion is complete.
